bchunk man page

bchunk converts a CD image in a ".bin / .cue" format (sometimes ".raw / .cue") to a set of .iso and .cdr tracks.

The bin/cue format is used by some non-Unix cd-writing software, but is not supported on most other cd-writing programs.

image.bin is the raw cd image file. image.cue is the track index file containing track types and offsets. basename is used for the beginning part of the created track files.

The produced .iso track contains an ISO file system, which can be mounted through a loop device on Linux systems, or written on a CD-R using cdrecord. The .cdr tracks are in the native CD audio format. They can be either written on a CD-R using cdrecord -audio, or converted to WAV (or any other sound format for that matter) using sox.

The output type depends on the input type (data is just copied). If the input is in ISO format, the output will be. On the other hand, if the input is raw audio data, the output will be CDR or WAV (the latter if -w is given).

It is advisable to edit the .cue file to either MODE2/2352/2048 or MODE2/2352/2324 depending on whether an ISO filesystem or a VCD is desired, respectively. The format itself does not contain this feature and in an ambiguous case it can only guess.

Tracks in ISO9660 CD filesystem format. Can be either written on a CD-R using cdrecord, or mounted (on Linux platforms at least) through a loop device ('mount track.iso /mnt/cdrom -o loop=/dev/loop0,blocksize=1024').

Audio tracks in native CD audio format. They can be either written on a CD-R using 'cdrecord -audio', or converted to WAV (or any other sound format for that matter) using sox ('sox track.cdr track.wav').
